INTRODUCTION
Thank you for purchasing a Wagan Tech®Slim Line™Power Inverter. With minimal
care and proper treatment, it will provide years of reliable service.
This User’s Manual describes the Operation, System Planning, Installation and
Maintenance of four Slim Line Power Inverters. These are: 1,000W (#2294),
1,500W (#2004), and 2,000W (#2482). These three inverters are similar except
for AC wattage output, DC input current, dimensions, and weight.
Your Slim Line power inverter converts 12/24/48 volt battery power into 115 volts
of AC power. You can use the inverter in your vehicle to operate many types of
appliances that use AC power such as TV, DVD player, laptop computer, power
tools, and lights for emergency or camping use.
In an industry where the actual wattage output varies so greatly, Wagan Tech
is proud to introduce TrueRated Power™technology. All our inverters feature
TrueRated Power. That simply means power tested and rated at a period of
24 hours continuous usage under full load. Many competing products claim
“continuous duty”, when they are often only 20 minutes of “continuous” duty at
full output. We also build our inverters with High Peak Surge rating to support
motorized appliance start up.
Read and understand this manual before installing and operating this inverter.
Keep this manual for future use.

FEATURES
• Two LED indicators display the operating status of the inverter.
• Multiple AC outlets allow for more than one appliance to be powered at
the same time.
• Mounting holes allow for safe stable installation.
• High Peak Power: Allows you to power appliances that require large initial
start-up wattage.
• Low Battery Alarm: The inverter sounds an audible alarm then turns itself
off if the battery becomes too low.
• Auto Shutdown/Reset Protection: The inverter temporarily shuts itself down
to protect itself from overheating.
• Overload/Short Circuit Protection: The inverter automatically turns itself off
if the connected load is too large or if it shorts.
WARNINGS
• Do not attempt to open the inverter enclosure. High voltage inside the unit
is the same type of power as your electrical outlets at home.
• Do not operate the inverter in or around water. The voltage of the unit
makes it an electrical shock hazard if operated in wet conditions. Do not
let any plugged in appliance’s cord get wet.
• Do not connect the AC inverter directly to another AC power source.
• Keep it away from children: The inverter produces power just like AC wall
outlets at home and it should be treated seriously.
CAUTIONS
• Do not use the inverter in a positively grounded vehicle.
• Allow at least 2 inches of clearance around the inverter for air flow.
• If you operate the inverter in a moving vehicle, you need to secure the
inverter to prevent it from shifting around while the vehicle is moving.
• If there is anything wrong with the inverter, disconnect all power.
• The following operations will damage and void the warranty of the inverter:
∗Reversing polarity by connecting DC cables to incorrect terminals.
∗Connecting the inverter to a power source greater than 15V/30V/60V DC.

REAR PANEL
All four inverters described in this manual all have two terminals for connecting
battery cables. One terminal is the Positive (+) terminal [red]; the other is the
Negative (−) terminal [black]. The Positive battery cable should have a Battery
Protection Fuse installed within one foot of the battery connection. The negative
cable can be directly attached to the negative battery terminal. In some cases, a
metal vehicle frame can be used as part of the negative cable to the battery.

MEASURING THE AC VOLTAGE
This inverter’s AC output is a modified sine wave (MSW) 115 volts AC. Your
household AC output is pure sine wave. The comparison of modified sine wave and
household AC is shown in the figure below.
(Pure sine wave)
This modified sine wave has a root mean square (RMS) voltage of 115 volts. Most
ordinary AC voltmeters are calibrated to read “average” voltage and assume that
the AC waveform will be a pure sine wave. These meters will not correctly read
MSW voltage, and will display about 20 to 30 volts too low. Any multi-meter
identified as “TRUE RMS” will accurately read MSW correctly.

BASIC OPERATION
• Turn ON the power switch that is located at the front of the inverter, and
the green LED indicator will light up as an indicator that the unit is working.
• Plug your appliance(s) into the AC socket(s) at the front of the inverter.
PLANNING THE INVERTER SYSTEM
Any large wattage inverter system requires planning before installation. There are
several steps to the planning process so the user must determine the following:
• Maximum inverter wattage required.
• Operating time (run time) needed between battery recharges.
• Battery bank capacity in amp-hours.
• Charger requirement to charge batteries within a practical time.
• Distance between battery bank and inverter.
DETERMINING MAXIMUM APPLIANCE WATTAGE
Maximum AC Appliance Wattage is the first factor in planning battery and
charging systems. Some background:
Large microwave oven specifications list cooking power (watts) and appliance
power. Appliance power is the AC load the inverter has to supply.
Most other electrical tools, appliances and audio/video equipment have labels
that list the unit's power requirements in watts. If the tool or device is rated in
amps, multiply the amps by 115 (115V AC) to determine the watts. For example,
a power tool rated at 4-amps will draw 460 watts.
Determine the wattage of each appliance you need to simultaneously operate.
Add all of the appliance wattages to obtain an estimated “total watts” number.
Remember to consider the start-up surge that motorized appliances will cause.
Do not exceed the surge rating of this inverter. This can cause immediate
overload shut down.
At maximum continuous output, this inverter requires a DC power supply (battery
bank) that can continuously supply required amps at 12V/24V/48V DC for the
duration of the run time.

CONFIGURING THE BATTERY BANK
To determine the minimum battery ampere-hour rating that you will need to
operate appliances from the inverter, and any DC appliances powered by the
battery bank, follow these steps:
(The following calculations are specific to 12V systems. For 24V or 48V systems,
a different calculation is required but the same principles should apply.)
1. List the maximum continuous wattage that the inverter has to supply.
2. Estimate the number of hours the appliances will be in use between
battery recharges. This will vary depending on appliances.
For example, a typical home-use coffee maker draws 500 watts during its
brew time of 5 minutes, but it only requires 100 watts thereafter to maintain
the temperature of the pot. Similarly, a typical use of a microwave oven is
only for a few minutes. Some longer operating time appliances are lamps,
TV’s, computers, and refrigerator/freezers.
3. Determine the total watt-hours of energy needed. This is done by
multiplying average power consumption in watts by hours of run time. For
example: 1,000 watts for 10 hours = 10,000 watt hours.
To get an estimate of the maximum current (in amps) that a battery bank must be
capable of delivering to the inverter, divide the load watts by 10. For example a
1,000 watt appliance load will need 100 amps at 12 Volts DC.
Using the 1,000 watts (or 150 Amps) for 10 hours example as above, then 100
amps is needed for 10 hours. This provides us with the basic amp-hours (AH) of
battery that is required. Ten hours at 100 amps equals 1,000 Amp Hours (AH).
This answer is just a beginning of configuring the battery bank because there
are additional factors that determine actual run time. These include:
• AC appliance load and time in use (basic AH)
• Cable gage and length (cable losses)
• Charge level of the batteries (between use, chargers have to be able to
fully charge the batteries)
• Temperature of the batteries (colder batteries provide fewer amps)
• Age and condition of the batteries (older batteries lose AH capacity)
• Compliance with turning off unnecessary AC loads

• Use of DC appliances and compliance with turning off unnecessary DC
loads
• If the inverter is installed in a vehicle and the alternator output in Amps
cannot supply enough current for the inverter, additional batteries are
required to supply the required current.
DERATING THE BATTERY BANK
Most lead-acid batteries have a rating expressed in amp-hours (AH). The most
common rating of AH is at the “20-hour rate”.
NOTE: Despite several Internet explanations, here is no relationship
between Cold Cranking Amps (CCA) and Ampere Hours (AH).
For example, if a 20Ah battery is discharged at an 1 amp rate, is will take 20
hours to discharge that battery. The terms “charged” and “discharged” relate to
actual battery voltage. This means that the output voltage of a nominal 12 volt
battery starts at 13.2 volts (fully charged) then drops to 10.6 volts (discharged).
If the load on the battery causes the battery to discharge faster than the 20 hour
rate, the capacity (AH) of the battery is measurably reduced (derated). Derating
is a major run time factor. Some benchmarks are as follows:
• If an 100 Ah Battery is discharged at 100 Amps, the battery capacity acts
like a 56 Ah battery.
• If an 100 Ah Battery is discharged at 200 Amps, the battery capacity acts
like a 32 Ah battery.
Again, both high discharge rates are faster than the 20-hour rate so battery
capacity seems lower.
INSTALLATION
Safe installation requires that a Battery Protection fuse is installed within one foot of
the positive (+) battery Terminal [red]. Use ANL marine fuses or equal because they
do not spark when they blow. Use an appropriate fuse holder for the fuse. ANL
fuse holders can be mounted so they do not move in a vehicle or vessel.
CONNECTING THE INVERTER
Loose DC (battery) connections will result in a severe voltage drop that can
cause damage to connectors, conductors, and insulation and can cause
sparking. Reverse polarity connection can permanently damage to the inverter.
Damage caused by reverse polarity will void the warranty.

WARNING:
Venting batteries produce explosive, corrosive gases. There is danger of
explosion. DO NOT connect or disconnect BATTERY cables directly after battery
discharge or recharge. Make sure that the battery bank area is well vented
before attaching or removing cables.
NOTES: All recommended cable gauges and fuse sizes are located at the rear
of this manual in the Cable Gauge Table. The table describes Cable Gauges for
lengths greater than supplied cables.
“Round Trip” refers to actual cable distance in feet from the POS (+) battery
terminal through the inverter and back to the NEG (−) battery terminal.
Crimp-on ring terminals are required on all cable ends. The cable ends need to
be stripped of insulation for ½ inch before crimping on ring terminals. Select
a crimp terminal size to fit the cable gauge and inverter and battery terminal
connectors. After crimping, make sure that the cable connectors are secure on
the cables so there are no loose connections.
CAUTION: Making an initial connection between the positive cable end and
the inverter’s positive terminal may cause a spark. This is normal and is a result
of capacitors in the inverter starting to charge. Because of the possibility of
sparking, it is extremely important that both the inverter and the battery bank be
positioned away from any source of flammable fumes or gases. Failure to heed
this warning can result in fire or explosion. Do not make the positive terminal
connection immediately after the batteries have been charging. Allow time for
the battery gasses to vent to outside air.
INSTALLATION PROCEDURE
1. Mount the inverter in a secure location. If the inverter is to be mounted
on a wall, mount it horizontally. Make sure that the front and rear of the
inverter has free air flow.
2. Make sure the cables are the proper gauge and have the fuse holder as
close to the battery bank’s Positive (+) terminal as possible.
3. Install the fuse in the Positive (+) cable (Refer to the Cable Gauge Table at
rear of manual).
4. Make sure the ON/OFF switch located on the front panel of the inverter is
in the OFF (O) position.
5. Connect the Negative (−) cable end to the inverter terminal and battery
Negative Terminal. Make sure you have good, secure connections.
6. Recheck and make sure the DC cable fuse is installed in the fuse holder.
